PROCESS OF MAKING EMBROIDERY ORNAMENTA'IION.

. original application filedJune 29, 1914, Serial. No. 848,023. Divided and this application'filed December 19 1914. Serial No. 878,096.

To all whom it may concern Be it known that I, RunoL'r Lone, a citizen of the United States, and a resident of Jenkintown, Montgomery county, Pennsylvania, have invented anImproved Process of Making Embroidery Ornamentation, (being a division of my application for patent filed June 29, 1914:, Serial No. 848,023,) of

, ornamentation constituting the subject of my invention, I make use of a machine employing two oscillatingneedles vibrating in a fixed path in line with their position. By rotating the goods upon which the stitches are laid with respect to a predetermined center disposed at some point intermediate the extreme throw of the respective needles, the stitches laid by these threads are caused to cross each other and produce a raised knot, the height of which may be easily regulated by the operator; the machine be ing stopped when the stitching has been efiected to the desired height. The diameter of the knot is regulated by the throw or oscillation of the needles, and their movement may be effected and controlled in the manner set forth in my Patent No. 1,193,803 dated August 8, 1916.

My present invention comprises the process of making my improved embroidery ornamentation, the embroidery as an article of manufacture being claimed in application Serial No. 8%,023 before referred to, of which this application is a division.

These and other features of my invention will be more fully described hereinafter, reference being had to the accompanying drawings, in which:

Fig. 3, is a sectional View illustrating the u manner in which the needles operate inv the fabricto lay the stitches thereon, and

Figs. 4,5 and 6, are enlarged sectional views.showingvarious steps in the formation of the ornamental knot.

In the production ofthe ornamental embroidery forming the subject of my present invention, I employ a sewing machine with a pair of vibrating needles, such as shown at 1 and 2, which needles are set in line with each other and vibrate in a single plane coincident with the plane of their position. The machine in which, these needles are mounted is equipped with mechanism that will enable the operator .to turn the work intermediate the limits of the throw or vibration of the needles. By this means, I am able to produce a novel form of embroidery which consists of a plurality of sets of raised stitches 3 and 4:, disposed upon the fabric 5, which stitches cross each other as the fabric is rotated and result in the formation of a raised knot or button-like figure. The stitches 3 and 1 are less in length than the diameter of the ornamentation produced by the same, and by reason of the fact that portions of said stitches cross the predetermined center, a greater bulk of thread will be left there and the height of such center will naturally be raised.

All of the stitches showing on the face of the fabric have loops 6 on the under side of the same, and these loops are caught by a single shuttle thread 7.

The effect of this ornamentation is materiallyheightened by the employment of threadsf different color; and the size of the l nots is; controlled by the throw of the '7 needles. 7 v

'The fabric niay-be movedcby means of a rotatable member such as shown, for instance; in my application for patent filed Dec. 31, 1913, Serial No. 8095798, or any other rotating means that will turn with the fabricwhen the operator mo vesithe tambour frame in which the fabric'isstre'tched;

This fabric- 'mov'in'g device'isadjustahle so I as to change the center-otthe same witlrrespec't to the throw of the needles and efiect circular orfnamentat ion of various sizes The needles may also be setvin different relationswith respect: to each other; changesjin thefthro'w of J the shuttle being correspondingly efprovidedwith an enlarged .space'13 at the This presser foot is em- "needles are 'in'the sameto insure proper 'c'oa'otion of the shuttle threadsand is raised when, thenneedles :are raised; having no feeding or other -movzingx eife'ct upon the fabric whichis whollynnder the controliof the-operator.

In the preferred :processfof producing @the ornamental embroidery forming the sub -jecto:c-of -m'yinvention, the raised knot or circular ornament is formed of continuous stitches from two independent threads laid by a PZITI'ZOIE vibrating needles upon the roytating fabric, which needles oscillate" or'vibrate in a'plane coincident with the plane of their settingy'so that -in the formation of such knot or-orn'aiment stitches will be laid simultaneously from {opposite sides of the shaped mass disposing upon a piece of material a plurality of annular rows or sets of radial stitches formed by continuous independent threads laid by a plurality of oscillating thread-carrying implements, simultaneously rotating the fabric on an axis that is crossed by the path of the thread-laying implements whereby the stitches that are laid upon the fabric will partially overlap stitches diametrically opposite therefrom substantially at the center of the embroidery ornamentation and form a relatively rounded concprojecting above the surface of the fabric. i
